' CHER, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, and ALBERT T. ZABRISKIE, a citizen of the United States, and .a residentof Passaic, in the county of Passaic and State of New Jersey, have invented a new and Improved Adding-Machine, of which the following is a full, clear, and exact description.

The invention relates to adding-machines, such as shown and described in the Letters Patent of the United States No. 816,342, granted to Nobyoshi H. Kodama and Abraham 1. Gancher on March 27, 1906.

The object of the present invention is to provide a new and improved adding-machine arranged to render the action of the number-wheels ositiveand without danger of the parts easi y getting out of order and to allow convenient and quick resetting of the v machine to Zero whenever it is desired to do so. 1

The invention consists of novel featuresand parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawin'gs, forming a art of this speclfication, in which similar c iaracters of reference indicate corresponding parts in all the views.

' Figure 1 is a face view of the improvement. Fig. 2 is a side elevation of the same. Fig. 3 is a face view of one end of the improvement, the casing being shown in section. Fi 4 is a rear face View of the same, the casing eing shown in section. Fig. 5 is a cross-section of the improvement on the line 5 5 of Fig. 3. Fig. 6 is a similar view of the same, parts be ing in different position. Fig. 7 1s a face view of one of the disk cams. Fig. 8 is an enlarged sectional plan view of one of the number-wheels and adjacent parts. Fi {3, is a transverse section of the same on the Tine 9 9 of Fig. 8. Fig. 10 is an enlarged sectional I plan view of part of the zero or resetting device. Fig. 11 is a cross-section of the same on the line 11 11 of Fig. 10, and Fig. 12 is a perspective view of the stand for supporting the adding-machine.

The casing A of the adding-machine con tains a frame B, in the upper end of which is secureda shaft C, on Which are mounted to turn loosely number-wheels D, D, D D D,

D, and D, each having on its peripheral face the numerals from 0 to 9 the number-wheel D representing unit cents, the number-wheel D tens of cents, and the number-wheels D D D, D and D representin unit dollar s, tens of dollars, hundreds of do lars, and thousands and tens of thousands of dollars. It" is, however, expressly understood that the number-wheels may rglpresent, es dolother denominations of money besi lars and cents mentioned.

The numeral which is on the top of a numberwheel--at the time is visible at a corresponding aperture A in the casing A to allow eoperator to read the aggregate amount of the sums added, as hereinafter more fully described. I

In order to turn each number-wheel manually and independently of the others, the following device is provided: On the. hub of each number-wheel D, D ,D, D D D and I D is secured asprocket-wheel E over which passes a sprocket-chain E, also passing over a sprocket-Wheel E mounted to turn loosely in one direction on a resetting-spindle F,

journaled in the frame Band extending with one end through one side ofthe casing A, the

outer end of the resetting-spindle F carrying a knob F to ermit. the operator of turning the s indle with'a view to reset the numberwhee s D, D, D D D D and D to zero, I

aperture A, the distance between t e adiacent numerals corres onding to the length of a link of the chain G and portions of the upper runs of the chain E appear through an openingE in the top of the casing A to allow the operator to see the numerals on'the face and to engage the link of the chain E by the use of a suitable tool in the hand of the operator to pull the The numeral-plates ICC by a spring 0 held in the recess N and the outer end of the spring 0. abuts against the under side of a cap N attached to the wheel N. Now by the arrangement described the wheel N is free to rotate on the spindle F in the direction of the arrow 0 when the machine is used as above described, it being understood that the ball 0 freely travels out of the groove. F and on the peripheral surface of the spindle F as long as the wheel N is turnedjn the direction of the arrow 0 by therotating wheel E travelin in the same direction. When it is desire to reset the adding-machine to zero position, then the operator takes hold of the knob F and turns the.

samein the direction of the arrow 0, so that the ball 0 when dropping into the recess N? is carried along by the back wall thereof, whereby the wheel N is rotated, and with it the ratchet-wheel E When this takes place, the ratchet-wheel E causes a travelmg of the sprocket-chain E, and a rotation of the sprocket-wheel E in the same direction,"

as above describedthat is, in the direction of the arrows c dand consequently the corresponding number-wheel is rotated in the Now as all the wheelsN on the spindle F are ultimately carried along on turning the knob F it is evident thatthe several number-wheels D, D, D D D and D finally reach a zero position-that is, the numerals 0 f of the several number-wheels will all appear in the corresponding apertures A.

The operation is as follows: Presuming that the aggregate amount of several sums already added by the use of the machine is ,three hundred dollars and thirty-two cents and the next sumto be added is five thousand two hundred dollars, then the operator by the use of a pointed tool engages the chain E for the number-wheel D '(hundreds of dollars) opposite the number 2 on the wheel-plate G and, then ulls this chain downward until the tool a uts against the edge A of the opening A The tool is then disengaged from the chain. The travel of the chain causes the rotation of the numberwheel G to the extent of two numbers, so

i that the numeral 5 of this number-wheel now appears in the aperture A. The operator now engages the tool with the chain E for the number-wheel D opposite the numeral 5, as the sum to be added calls for five thousands of dollars, and then the operator pulls this chain downward until the tool abuts against the edge A and this move- .n'ow registered is $5,501.16.

ment of the chain causes the wheel I) to turn from zero position until the numeral 5 appears in the corresponding aperture A. The total amount now indicated at the openings A appears as $5,500.32Z-that is, the aggregate amount of the original sum of three hundred dollars and thirty-two cents and that of the amount added, five thousand two hundred dollars. 1f the next following check is for, say, eighty-four cents, the operator-engages the tool with the chain E for the number-wheel D opposite the numeral 4 of the corresponding numeral-plate G and then pulls the chain downward, as previously described, so that the wheel I) is turned until the numeral 6 appears in the aperture A. The 0 erator now engages the tool with the chain or the number-wheel D opposite the numerahS of the corresponding numeral-plate and then pulls the,chain downward. The number-wheel D is turned a distance of eight numbers, and in doing so the wheel stops with the numeral 1 displayed in the opening A, and as the wheel was turned from "9 to 0 it is evident that its pawl H engaged the ratchet-wheel of the next following number-wheel D so that the latter was turned to the following number that is, to the number 1-,which now appears in the opeiiing A, and the total amount When it is desired to reset the machine so that 0 of the several wheels D, D, D D, D, and l) appears in the openings A, it is only necessary for the operator to turn the knob F in the direction of the arrow 0, so that the spindle F is turned, and with it the several wheels N and ratchet-wheels E as previously explained, to cause the chain E i s rotate the ratchetwheelsE and the numberwheels D, D, D D D ,and D until "0 of the several wheels appears in the openings A. The machine is new again ready for adding other sums.

Instead of working the machine from the right to the left, as described.that is, starting with the unit centsit may be actuated from the left to the right, the final total appearing through'the openings A in either case,

In practice it is desirable to place the easing A into a stand P, (illustrated in Figs. 1, 2, and 12,) and this stand P is provided with two sideplates P P connected with each other by cross-bars P 1 of which the cross-bars P are ada ted to support the hack of the casing A, W Ille the front thereof rests against, flanges P formed on the sides P and P at the front edges thereof, the said flanges P being curved downwardly and inwardly at the bottom toform a seat for the bottom of the casing A. The side P is provided with an elongated slot P for the passage of the outer end-of the s indle F, so that the knob F projects from t e outer face of the side 1?
